Abstract: A target structure for generation of x-ray radiation may include a heat sink; and a target element for electrons to strike, the target element being in the heat sink to cool the target element, wherein the heat sink includes a metal-diamond composite material.

Abstract: A stationary anode for an X-ray generator, in particular of an X-ray imaging device or an X-ray therapy or spectroscopy device, includes a main anode body and an internal cooling duct, running in the axial direction, for conveying a cooling fluid to a heat exchange surface of the main anode body. A nozzle, disposed at the end of the cooling duct, is inventively positioned with respect to the heat exchange surface via stop elements such that, between the heat exchange surface and the nozzle, a gap is formed which extends over an angular range of 360° about the axial direction.

Abstract: An electron accelerator that generates a photon beam with an energy of more than 0.5 MeV by means of an electron beam charging a target has a vacuum chamber with an intake opening and an exit opening, and an electron source at the input side. The target is arranged outside the vacuum chamber in the region of the exit opening in a housing in which a window is present that is permeable to photons and that is arranged opposite the exit opening in the beam direction of the electron beam. The target is permeated by at least one cooling channel.
